摘  要:目的:研究番荔枝科植物黄花紫玉盘(Uvaria kurzii)中的化学成分。方法:采用硅胶和凝胶柱色谱方法进行分离纯化,利用谱学和合成方法鉴定化合物的结构。结果:分离得到一个新的二苯甲烷类衍生物(1)和5个已知贝壳杉烷型化合物(2-6),分别鉴定为双(4-辛酰基苯基)甲烷(1),对映-16-贝壳杉烯-19-酸(2),大花酸(3),对映-15-贝壳杉烯-17-醇-19-酸(4),对映-16α,17-二羟基贝壳杉烷-19-酸(5),和对映-16β,17-二羟基贝壳杉烷-19-酸(6)。结论:化合物1是一个新的二苯甲烷类衍生物,化合物2-6皆为紫玉盘属植物中首次分到。离体大鼠心衰试验表明,与对照药哇巴因比较,化合物1能增加冠脉血流量和增强心肌收缩力。AIM: To study the chemical constituents of Uvaria kurzii (King) P. T. (Annonaceae). METHOD: The chemical constituents were isolated with silica gel and Sephadex LH-20 column chromatography and their structures were elucidated by spectroscopic and synthetic methods. RESULTS: A diphenylmethane derivative (1) together with 5 known ent-kaurane diterpenoids (2-6) were isolated and identified as bis (4-octanoylphenyl) methane (1), ent-kaur-16-en-19-oic acid (2), grandifloric acid (3), ent-kaur-15-en-17-ol-19-oic acid (4), ent-16α, 17-dihydroxykauran-19-oic acid (5) and ent-16β, 17-dihydroxykauran-19-oic acid (6). CONCLUSION: Compound 1 was a new diphenylmethane derivative, and compounds 2-6 were isolated from the genus Uvaria for the first time. Bioactivity test on isolated rat heart failure model suggested 1 could increase coronary blood flow and myocardial contractive power compared with positive control ouabain.
